To provide a pressed type angular ball bearing 1, which has a non-separative structure of a pressed outer race 2 and a pressed inner race 3 without increasing the number of components, and can be easily handled.
The pressed type angular ball bearing 1 has a plurality of balls 4 arranged between the curved tilting surface 25 provided on one end side of the pressed outer race 2 in the axial direction and the curved tilting surface 35 provided on the other end side of the pressed inner race 3 in the axial direction respectively, and a line of action 10 tilted with respect to a rotation axis 11. Limiting portions (second connection portions) 26, 36 for limiting the axial movements of a plurality of the balls 4, when both of the outer race 2 and the inner race 3 have relatively moved in the axial direction, are provided on the other end side of the pressed outer race 2 in the axial direction and on one end side of the pressed inner race 3 in the axial direction. The respective limiting portions 26, 36 are provided with an auxiliary outer raceway surface 27 and an auxiliary inner raceway surface 37 (second curved tilting surfaces) for the balls 4 such that the line of action 10 tilts in the direction opposite to that of the line of action 10 described before.
